Because for me, '60s pop music is amongst the most complicated or complex music because it has so many resonances which strike you. The music itself is often simple, but the way that I interpret it, or the way I think it's interpreted culturally, is very complex.

What I liked about doing a soundtrack is that it's almost the opposite of any kind of normal recording that a band does, because it's very much a restricted, narrow... And I kind of like that, I find it exciting to work within these things.
